    Sending two files in one command?

    IS there a quick way to send two files below in one command?

    ./tossfile hostip file1.c
    ./tossfile hostip file2.c

    while I am running the server as ./catchfile

    I can send one file but for some reason I can't send file1.c and file2.c at the same time.....

    I don't think tossdir will work. I am trying to "socket program"

    When I run this code on one machine:
    ./catchfile

    I then run this code on the other machine:
    ./tossfile host IP catchfile.c

    The ./catchfile program would produce this response:
    host(192.168.236.111:48591): 1/1: catchfile.c

    I am trying to do: ./tossfile host IP tossfile.c catchfile.c in one command.
    What is the command to do this is my question........

    All I know if the main loop is altered in the client program, I believe the ./tossfile host IP tossfile.c catchfile.c will work but I don't know what to alter.

    Well within the server file, I needed to commented out the following part. Everything works now.

    Code:
    }
    	close(fd);
    	//close(sd);
    }
